David - the mic thing is a bit tricky. You have to set it up under the settings menu to pair it to the PS3. Then, (the step I always missed), you also have to set it up under "chat" (one of the menu options to the far right of the menu bar in the PS3). From that menu, you have to go into some sort of settings menu and select the Bluetooth headset you just paired as the mic device for chat. From that point in, it should work auto-magically every time it's turned on.

I tried the Mirror's Edge demo on the PS3 tonight. It was pretty cool. I like the graphics, and the feel of the gameplay is cool when you can actually pull off the moves. I have to admit my playing was pathetic and took multiple attempts at most parts. I'm just not the player I used to be.
